 * Test that pthread_mutexattr_setpshared()
 *
 * The default value of the 'pshared' attribute is PTHREAD_PROCESS_PRIVATE.
 *
 * Steps:
 * 1.  Initialize a pthread_mutexattr_t object with pthread_mutexattr_init()
 * 2.  Call pthread_mutexattr_getpshared() to check if the process-shared 
 *     attribute is set as the default value PTHREAD_PROCESS_PRIVATE.
